Hello, I'm trying to get an Access Token through the STET PSU OAuth2 framework. Few weeks ago, it worked fine. But today, I got an HTTP error code 502 after having successfully passed the SCA.
502 Bad Gateway: Registered endpoint failed to handle the request.
It seems that the issue appears when the redirection to my OAuth2 redirect URI is performed.
I use the URL "https://api.eu.apiconnect.ibmcloud.com/cmarcoliukibmcom-open-banking-agg...". My redirect URI is "http://localhost/authentication".
Any help is welcome.
